I'm trying to speed up my PowerEdge R300 by upgrading its two hard drives from SATA to SAS. It has the base PERC controller. I have two Dell (Seagate Cheetah) 400 GB drives. I see I need different SAS controller cables, so I ordered a JW523 SAS cable as well. Do I need anything else? Does this cable also handle power? I thought I'd check with the community before I continue ordering parts one by one.
Are you upgrading from 7200rpm SATA to 10k or 15k SAS? It could make a little difference in performance, but why not go with a pair of Intel S3710 400GB SSDs from Ebay? You can pick these up for less than US$150 and they'll run circles around any harddrive.
The S3710 is a high endurance SSD and cannot be compared to your common desktop/laptop SSD; they are designed for server usage.
Note that you would probably want to be using an H-series PERC and not a PERC5 or PERC6 as those pre-date SSDs and you won't get to benefit from the performance potential and lose several other features too. I'd suggest looking at at least a PERC H700, but you may need to check the SAS cable options.
